Sustainability and the environment
Strong environmental management is critical for our business and for society. Our “Protect Tomorrow, Today” expectations underscore our dedication to improving environmental performance, including reducing emissions and increasing energy efficiency.
The Company conducts regular reviews of all aspects of its business to ensure compliance with environmental laws, regulations and internal policies. We implements various pollution control and other environmental impact mitigation measures, including the use of ExxonMobil technologies that reduce emissions and conserve energy. Adoption of the ExxonMobil’s Global Energy Management System (GEMS) equips the Company with a comprehensive and rigorous system of operational, maintenance, and design best practices for energy management. Capital investments are continuously made to improve the reliability and efficiency of the refinery, as well as pollution control and other equipment to effectively manage environmental performance. Regular maintenance is performed on all units within the refinery to maintain safe and reliable operations.
The Company proactively manage our operations toward reducing greenhouse gas intensity to ensure minimum impact on the environment and surrounding communities. We also implement various pollution controls and other environmental impact mitigation measures to manage emissions as required by applicable law, including applying advanced technologies to reduce emissions and conserve resources.
The strategic location of our refinery at Sriracha provides us access to a convenient product delivery network that allows us to distribute products in a cost effective manner, including a multi-product pipeline. The pipeline, to which our refinery is connected, is capable of transporting jet fuel, diesel, and gasoline. Pipeline transportation is the safest and most efficient means to move products from the refinery to terminals strategically located near demand centers for our products.
We seek opportunities to reduce the air emissions associated with our operations and the products we deliver to increase shareholder value and meet regulatory requirements. All three cogeneration gas turbine generators at the Esso Sriracha facility have low carbon dioxide emissions compared to conventional electricity generation. Other examples of how we have reduced emissions from our operations involves the implementation of leak detection and repair (LDAR) program, which is one of the initiatives to maximize fuel gas utilization, and the use of low NOx burners.
As a result of these efforts, Esso Sriracha refinery’s emissions of volatile organic compounds (VOCs), sulfur dioxide (SO2) and nitrogen oxides (NOx) have decreased more than 60 percent over the past 10 years.
Spill Prevention and Response
The ability to respond to emergencies promptly is critical, and the Company conduct extensive training and drills to prepare for such situations.
The Company believes effective emergency preparedness requires competent response teams. To that end, we establish strategic emergency support groups (ESGs) to develop and practice emergency response strategies and assist field responders. We routinely train ESG members, a wide variety of our employees, on a range of possible scenarios, including simulated spills, fires, explosions, natural disasters and security incidents.
The Company takes a disciplined and structured “command and control” approach to emergency preparedness that is based on clear communication. The Company established emergency support groups (ESGs) at the Refinery and at the Country level to ensure readiness and preparedness for emergency response in country. At the Sriracha Refinery, we conduct four exercises per year in various possible scenarios. Regardless of the size of an event, our facility and business unit also have access to a wide array of trained responders, including our regional response teams (RRTs), which provide rapid tactical support when needed.
In Thailand, we have about 30 Thai employees who are members of ExxonMobil’s RRT. All of them participated in RRT training together in October as part of annual training programs.
The Company implemented measures to preserve fresh water sources and treat waste water. Our refinery operations use and recycle fresh water produced by our two desalination plants, thus saving natural fresh water resources and energy. Our water treatment system features various units to separate oil from the water, including oil skimming tanks, an oily water separator and an induced air floatation unit, to remove oil from waste water, and an oxidation pond. In 2011, Esso Sriracha refinery constructed the biological oxidation (BIOX) wastewater treatment system at the refinery to ensure that the effluent water quality standards are met. The new BIOX system became fully operational since June 2014.
All wastes from either industrial waste from the operations or domestic wastes from offices are manage by Global ExxonMobil Standard. Each steps of the waste management has been focus for example; Know what wastes are generated, Know how each waste should be managed, Segregate wastes according to risk and disposal method, Send waste only to approved disposal sites, Track wastes from source to disposal and Minimize waste generated. Since 2012, about 90 percent of disposed wastes from the Refinery sent to beneficial reuse.
EnvironmentReliable and affordable energy is essential to human progress. At the same time — like all industrial processes — energy development involves risk. ExxonMobil considers risk at every stage of development, and we continuously work to reduce environmental impacts. Rigorous standards and good practices that consider the needs of the communities where we operate guide our efforts.
